CHRISTIAN NEUMANN, OF ST. LOUIS, MISSOURI.

, BLOWER,

Specification of Letters Patent.

Application filed January 11, 1915. Serial No. 1,573.

To allwkom it may concern:

Be it known that I, CHRISTIAN NEUMANN, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Blowers, of which the following is a specification.

This invention relates to improvements in Blowers and has for its objects a revolving member axially mounted in a housing and its periphery equipped with a plurality of deflecting paddles each having a projecting wing or extension which creates a vacuum causing the air to pass out of the revolving member and into the housing with great 1 5 velocity.

My invention is an improvement over United States LettersPatent No. 1,086,686, issued to me February, 10th, 191i, and the essential feature of this improvement over said Letters-Patent is the particular construction of the wings or elongated projections located on the deflectors.

By continued experimenting, and after having built an operating blower of the type as is shown in the accompanying drawing, I found a wonderful and effective result in producing an air current of a greater volume and pressure than from the blower under Letters-Patent No. 1,086,686 which is effective in itself.

Figure 1, is a side elevation of my invention showing a part of the housing and re volving member broken away and in section. Fig. 2, is an enlarged sectional view of one section of the revolving member. Fig. 3, is a detail inverted sectional perspective of one of the paddles and its elongated projection.

My improvement consists of a revolving member 4:, mounted on an axis or shaft 5, supported in the usual bearings, preferably one on each side of the housing 6, in which the revolving member is housed.

The revolving member consists of a hub 7, from which radiate spokes 8; to said spokes and on the outer sides are plate rings 9, partially closing the sides thereby forming a central inlet or an passage 10, through which the air under atmospheric pressure is permitted to enter the revolving member. Each spoke is provided with a paddle 11, which extends from ring to ring and of the height thereof, thereby dividing the member into separate divisions or compartments which are each in turn again divided into a plurality of divisions by the auxillary paddles 12. The main paddles 11, are each provided with a deflector 13, located on the rear side of and at right angles to the main paddles and extending into the compartments to a point approximately midway between the main paddles and from hing to ring, and are firmly secured to the rings 9, in a manner as that shown. The auxiliary paddles 12, as will be observed successively increase in radial breadth, the shortest being immediately in front of the main paddle 11. Each of these auxiliary paddles are provided with tapered deflectors 1 1, the bottom member 15, being at right angles to the paddles and located a short distance away from the peripheral edge. On these n1emhere 15, are firmly attached angle extensions 16, consisting of an elongated web 17, a base flange 18, and end pieces 19. These angle extensions are secured to the members 15, by rivets passed through the flange 18; the extensions 16 being shorter than the width of the members 15, so that the portion project ing beyond the periphery will not contact with the side of the housing in the event of side thrust caused by the wearing of the shaft of the revolving member and the journal boxes.

The placing of the auxiliary paddles, with their deflectors prevent the creation of eddy air currents, but to the contrary creates a vacuum permitting the air to flow in lines indicated by the arrows in Fig. 2, striking the inclined deflectors and passing out through the outlets 20, being sucked forward as indicated by the arrows by a vacuum created by the angle extensions, thus driving the air uninterrupted toward the housing outlet 21. With the additionalangle extension the air passing out of the se'v- I eral compartments is conveyed forward instead of passing out on a direct line.

Having fully described my invention what I claim is:

A blower, comprising a housed axially Patented June is, ieie.
